"Our party is deeply concerned about sentiments expressed by the Tamil people. We share their sentiments and are completely with them," the party said in a tweet on its official account.

At the same time, it added, "On matters of external policy, we have, from the beginning, always left it to central government in moments of crisis. We will do the same on this occasion." The statement implied that the party will stand by whatever position the government takes with regard to the resolution on Sri Lanka at the UNHRC.

Sources said that prior to the Trinamool statement, Parliamentary Affairs Minister Kamal Nath had reached out to Mamata Banerjee by talking to her on Wednesday morning. Banerjee is understood to have conveyed the same sentiment to him as well.
